I saw this in the hills of PA...It looks like it was a tug for the AF...

Yeah, that's an old school "tugger" I believe... not sure if they are actually "Rocks", they're planetary style axles...
 
Can't see the pics but it sounds like a tug truck with planetary ZF axles. Also has a 208 locked in lowrange or something. Not exactly very useful unless you need to pull a plane around.
 
Yeah, top speed is about 13 mph or something ridiculous. The diff gearing is about 20:1 final.

They are airplane tugs built for the military. They have a 6.2, th400, 208. The axles are German ZF APL345 planetaries, 4 wheel steer, 22:1 ratio. The truck started life as a 2wd. The suspension is solid mounted in the center of the axles.
 
Well...you can move airplanes around with it!

Guy on a Michigan forum I used to read took one and turned it into a mud truck. Got rid of the bumpers, put a leaf spring suspension under it, fixed or put a different T-case in it so 2wd and hi worked, and put 44" Swampers on it. Said it was still ridiculously low geared. Last I heard he was looking for tractor or large military tires. Like 50"+ big.

I like his motivation, but he doesn't sound like hte brightest crayon in the box....

Sounds like a cool base....but the gearing woudl kill it. Too lazy to run the numbers, but for mud, doubt 50" tires woudl spin fast enough......
 
I think he went...like a lot of others automatically assume...squarebody GM basicness and "buildability", sound drivetrain, BIG AXLES, wears large tires from the factory...MUD BOG MASHEEN!

He could always add about 3' of lift and put it on huge agricultural tires but it'd be awefully short...

And not have the power to turn them fast enough.

Not good when you tire size is limited to the size of the wheelbase....so your tires don't hit each other!
 
I would take one set.
No need for mud bogs but rock crawling would be good with these, and being both steering axles would help with the bigger tires, you can easily put 60" tires on there. AG tires.
 
I could use that at my shop to push dead power strokes in The bay.....

Would need 20:1 to push those turds, and I would probably put 100,000 miles a year in it
